Study on Interpretation Method of Multistage Fracture Tracer Flowback Curve in Tight Oil Reservoirs

Dianfa Du,
Fanghui Hao,
Yuan Li
et al.

Abstract: Multistage fracturing is widely used in the development of tight oil reservoirs, and the fine description of postfracturing fracture networks is a challenge in tight oil reservoir development. Based on the formation mechanism of dual-wing fractures and the principles of tracer flowback, a mathematical model for tracer concentration in dual-wing fractures is established by considering the convective diffusion of the tracer within the fractures. An interpretation method for tracer flowback curves, utilizing a co… Show more
